Dear IGS colleagues,
Two weeks ago, I sent an e-mail suggesting to remove
http://igscb.jpl.nasa.gov/mail/igsstation/2005/msg00013.html
a number of stations from the reference frame realization
including GOUG.

More recent data has indicated that GOUG has resume
more "normal" coordinates behaviour.
Station # N-E H
1203 - 1302 GOUG 10 3.1 24.0
1303 - 1305 GOUG 3 3.2 7.7
I suggest to include it back.
YAKT
For the past two winters (~Wks 1205 & 1255), the station
has been experiencing anomalous residuals for a few (~6) weeks.
The effect was about 10m in the North and East components, the
height component was affected to a lesser extent. This winter
the station is also experiencing anomalous behaviour. This time,
the effect is about 25-30 mm in all 3 components. The station
has been temporarily removed from the final product since Wk 1300.
Since the anomaly is worse than the previous years and do not
show any sign of improvement, I suggest to remove it...
at least until it resumes more "normal" behaviour.
Best Regards,
Remi,
